Rhubarb-Pistachio Bundt Cake With Rose Glaze

Preheat oven to 350 °F. Butter and flour Bundt pan, tapping out excess flour. Rub together granulated sugar and lemon zest with your fingers in a large bowl until fragrant. Using an electric mixer on medium speed, cream lemon sugar and 3/4 cup butter until light and fluffy, about 4 minutes. Add eggs 1 at a time, scraping down sides of bowl and beating well between each addition. Beat in rose water and vanilla extract on medium-low speed until just combined. Whisk 2 1/4 cups flour, salt, baking powder, and baking soda in another large bowl. With mixer on low, add dry ingredients to lemon sugar mixture in 3 additions, alternating with yogurt in 2 additions, beginning and ending with dry ingredients, scraping down sides and bottom of bowl as needed. Fold in pistachios. Cut rhubarb crosswise into 2 1/2" pieces. Using a mandoline set to 1/4" or a very sharp knife, slice rhubarb lengthwise, maintaining as much red skin on stalks as possible. Pour one-third of the batter into prepared pan and smooth surface. Add half of the rhubarb, nestling pieces side by side to form a thick ring on top of batter. Pour another third of the batter on top of rhubarb layer; smooth surface. Repeat with remaining rhubarb and batter. Bake cake until the surface is cracked and golden brown, springs back to the touch, and a tester inserted into the center comes out clean, 50 –60 minutes. Let cake rest in pan 10 minutes, then turn out onto a cooling rack.
